Results

            When the drop of soap solution was put in the water with the pepper. The soap pushed the pepper to the sides of the bowl. The soap made a 4½-inch hole in the pepper, which is where you get the measurement for the diameter of the circle. Then to get the molecular mass you take the volume of the drop of soap and multiply it by 0.000125 to get 0.0000025. After that you need to get the amu weight of the molecule sodium stearate, and with that information and the number mole we can find how many molecules are in the circle.

Conclusion

            This experiment teaches you the importance of Avogadro’s number; if we did not have this number this experiment would not be possible. Some of the things that I changed in the experiment was the way that I got the volume of the drop of soap. Instead of counting how many drops it takes to fill 10mL. I filled 1mL three times and averaged how many drops it took.
